A new series of Fe4S4 active-site analogues for high-potential iron–sulphurproteins have been prepared from [Fe4S4(SBut)4]2– and macrocyclic tetra-aza tetrathiolligands where the active-site cores are composed of an intramolecularhydrophobicdomain formed by 28-, 32-, 36-, 40-, and 44-membered rings having methylene backbones. The compounds were obtained in good yields (70–90%) as black powders
